(defn mappify
  "Takes a sequence of row vectors, as commonly produced by csv parsing libraries, and returns a sequence of
  maps. By default, the first row vector will be interpreted as a header, and used as the keys for the maps.
  However, this and other behaviors are customizable via an optional `opts` map with the following options:

  * `:keyify` - bool; specify whether header/column names should be turned into keywords (default: `true`).
  * `:header` - specify the header to use for map keys, preventing first row of data from being consumed as header."
